Honestly, I wouldn't put it past being Lionel himself. The length of the video which is just endless blabbering about nonsense (the screenshot tells the entire story of the 8 minute video), actually caring about the Xeno x Spudsy drama in [current year]... that's pretty Lionel coded. The only thing that is making me think it's not him is the lack of vulgarity, Lionel curses basically every sentence.
Even if this is cold hard facts, talking to someone a month before they turn 18 is not the same thing as grooming a minor and only someone deranged would go as far as to stalk child photos of someone from facebook and make an 8 minute video on that to prove this point. Mind you, this is something that Spudsy herself has said was not an issue / didn't happen, so to white knight to this degree is just... well, it makes me think it might actually be Lionel. Plus the whole, first post, new account, etc etc.
I tuned out of most of this drama when it stopped being funny and mostly started being sad (and when I fell off of xiv, though OC is looking p. fun) so that's my best 2c on it.
